Abstract (en)
[origin: WO2006048374A1] The invention relates to a method for receiving a data signal by N<SUB>R</SUB> receiving antennas. The data signal undergoes, before transmission, a channel coding and is transmitted on N<SUB>T</SUB> antennas each transmitting a portion of this signal. Upon reception, the transmission channel between the transmitting antennas and the receiving antennas is estimated. According to the invention, a method of the aforementioned type involves at least one iteration for improving an estimation of the received signal according to the received signal and involves a preceding estimation of said received signal, comprising the following steps: filtering this received signal; determining an interference affecting the received signal while furnishing an estimated interference; subtracting this estimated interference from the filtered signal whereby obtaining an improved signal; equalizing this improved signal and furnishing an equalized signal, and; estimating, from this equalized signal, the emitted data signal, called the estimated signal.
